IPC: F16K31/00
Filed: 1989-09-14
Abstract: PURPOSE: To prolong service life of a thermally controlled valve by constituting in such a way that a spring consists of a belleville spring, this spring is brought into contact with an end face of a diaphragm member to support a scope of an outer fringe part of the belleville spring on a support member, and a scope of an inner fringe part of the belleville spring acts on a closing member. CONSTITUTION: In a closing stroke, a diaphragm member 7 leaves a wall member 6 and a disc 19, and the member 7 comes into contact with a belleville spring 14 and a head part 12 of a closing member. When an internal pressure in a storage chamber 8 rises properly, a closing member 9 moves in the direction of closing against the action of the belleville spring 14 through the member 7 and adheres closely on a valve seat 10 and comes into contact therewith. The member 7 is supported over a large area by the spring 14 and the head part 12 the closing member during the whole closing stroke and motion. A closing force generated due to a difference in pressure between the storage chamber 8 and a high pressure side 1 is received by the spring 14. Consequently, since the member 7 is not subjected to a load and receives a comparatively small bending stress generated by a stroke motion merely, the member 7 can be used in case of a large difference in pressure, thereby prolonging service life greatly.
